So the genius Mazda dealer filled our new car with 87 octane (lol), figured we'd do a few dragy runs to help burn the tank off. Best of which is attached. Apparently they rate the engine for 225hp on 87 octane, 250hp on 91+ octane, so we'll dragy 91 octane next before we install the JB4 prototype.

91 octane baseline runs, not bad! About as fast as a tuned Honda Civic 1.5T.

Subscribing to this thread.

I have a 2018 Mazda 6 with the 2.5t and am excited to see development on this engine.

For V1 systems adding in the new MAF connection, first update the JB4 to the v4 or new firmware in the app. Select option bit6 on and save settings so the JB4 is aware you're a V1 application. This can be done any time after the install also if you forget to do it before.

Then open hood, lock doors, hide key, wait 5 min for ECU/car to power down.

Open the JB4 enclosure and the pins plug in to the JB4 spots. There are little numbers next to them. Check twice before plugging a pin in as they can only be removed with a dsub removal tool. See reference photo below. It's best to route the pins through the rubber harness grommet so they seal nicely when the enclosure is closed.

Purple is male connector goes to pin 8 on DB25
Blue is female connector goes to pin 14 on DB25

Finally attach the MAF connection to the MAF sensor and original harness.

Whew, at first, I thought you were going to say the 6 wouldnít be applicable due to the minor differences. Glad to hear that tuning will be the same!

Terry @ BMS 12-07-2020 12:49 PM

Making some decent progress here. Was able to add knock and learned knock factor to the logging channels. Making good progress on fuel control also. Once the logging is buttened up I'll start posting up some logs.

Issue cropped up with an o2 sensor so testing is on hold a few days as I wait for a new factory o2 sensor to show up. :lol

Crap turns out its on world wide backorder, need to wait 3+ weeks now. :(

LOL, glad you're having fun!

Soundsophist 12-24-2020 07:22 PM

I have a 2019 Mazda 6 with the turbo. I’m VERY excited about seeing this develop! The stock tune absolutely falls on its face above 4500rpm.

Terry @ BMS 12-24-2020 10:41 PM

Yes the top end what I'm hoping to improve once we finally get fuel control sorted out. The car runs 10:1 from the factory for most of the power band!

BMS has a new AWD dynojet scheduled to be installed early Feb so we'll have to wait until then for factory and tuned dyno numbers.

RayRah000 01-12-2021 10:23 AM

Any updates Terry??

Terry @ BMS 01-13-2021 08:45 PM

Our car has been parked the last 3 weeks waiting for an o2 sensor to show up from Japan. Such is life during COVID. =/

RayRah000 01-14-2021 03:24 AM

3+ weeks to get an O2 sensor...thatís not good...to think the dealer would have them in stock

Terry @ BMS 01-15-2021 02:08 PM

Yep pretty lame. But what can you do. They are not available anywhere in the USA right now.

tegxsi 01-15-2021 03:47 PM

The 2.5T has been around since 2016.
So the o2 sensor used in the CX9, CX5 or 6 2.5T won't work?

Is the part#?
NTK 27069 {#PY8V188G1}

Terry @ BMS 01-15-2021 03:55 PM

Tried it, doesn't work.

ecoil 01-17-2021 01:06 PM

Just registered to show my support - very much looking forward to an option for the 2.5T!

Terry @ BMS 01-18-2021 11:01 AM

Now they are telling me early to mid Feb. What a total waste of time lol.

Jaydawson46 01-18-2021 11:56 AM

Think it's most Japanese parts.... waiting on seat for my Yamaha Mt07 from UK as it's not sold in US. Just called em directly this morning to follow up and they said Yamaha told them they are over month behind. We will have to learn to be patient during this covid crap. Oh, and I'm following as well...can't wait to see the results... gonna purchase asap for our Mazda 6 2.5T!!

Terry @ BMS 01-18-2021 03:21 PM

On the plus side I got the connectors I've been waiting for to do the direct boost solenoid control, so can't wait to dig in to that. It's the last major piece other than oxygen sensor control we need to maximize power with the JB4.

Our new AWD dynojet should show up sometime next month too.

Mazdanation 01-18-2021 10:27 PM

registered for updates. Can't wait to see what the 2.5t can do with tuning.

2021 Turbo 3
 
As an owner of the 2021 Mazda 3 Turbo in a Hatchback, I'm very excited to see it being developed. I've been waiting patiently for parts and tuning solutions, and came across this forum through the Burger site. I had a 2019 I bought in 2019 loaded up with everything from CS, now I have to wait again, haha. Already working on the sound system and matting.

Hope development is going well, I'll be eagerly awaiting updates.

Terry @ BMS 02-09-2021 10:41 AM

Just as a development update we finally got our car back last week with the new o2 sensor. I was able to get EWG control up and running, but it's looking like we need to take MAF control to do everything we want to do. MAF is running a SENT signal rather than digital or analog so it's a little tricky, but we're making progress.

2018Mazda6 02-09-2021 10:53 AM

Thanks for the update Terry! Good luck.

That's great news on the catalytic and o2 sensor! Out of curiosity, what is a SENR signal?

It's a newer protocol for handling sensor inputs, one that is a little more complicated for us to process. But we have other SENT based platforms so not a huge deal. Just a little extra time to sort out how to handle it. :burnrubber:

Hello Terry.

Will this eventually be available for the 2017 Mazda CX-9?

We plan to cover the entire platform, although technically some of the older models will be a different part number as they appear to use a different TMAP sensor.

Post up photos of your MAP/TMAP sensor and I can verify what you'll need.

Eagerly awaiting this product because my 2021 Cx-5 turbo needs some help in the power department...

jcrout7992 02-17-2021 05:11 AM

Terry,
The majority of the Mazda CX-5 owners with the 2.5T have experienced a consistent power loss in 1st and 2nd gear when the temperature drops below 20 degrees Fahrenheit. It’s independent of traction, precipitation, engine and transmission temps, you name it. When it drops below 20, there’s no boost until 3rd gear. If you heat soak the engine when it’s less than 20 outside you’ll get normal power for the first pull. After that it drops back down to nothing. Have you seen anything like that so far?

Not something we've experienced but it hasn't been that cold. Photos of your MAP/TMAP connections? We can get a basic system up and running on those now I think to start collecting more tuning data.

On the CX models I think the TMAP is mounted to the top of the intercooler, likely under a plastic cover, as shown in this IC install photo we saw online. I want to confirm it's the same 4 wire sensor on your manifold.

Attachment 100489

Compared to the Mazda3 which has a 3 wire connection for TMAP which is easy to reach from the top, to the left of the airbox.

Beta Testing
 
Any idea when you think there may be some beta products able to be released to us tech and data driven folk? I just got done with a complete overhaul of the audio system from the factory amp out (JL Fix86 and Twk88) and am ready for my next project, lol. There are supposed to be intake and exhaust systems coming along soon too from Corksport. ETA on exhaust is completely unknown atm as it's supposed to be a full ******** and high flow ***/no *** then back. But intake 'should' be this spring. I'm eager to get my hands on the system.

Terry @ BMS 02-20-2021 10:39 AM

I have a basic system up and running but before we can really release something need to evaluate EWG control, MAF control, and maybe oxygen sensor control. But for those who don't mind helping out with logging, plugging in some addl wires to the PNP connector when we added in additional loops, etc, we could open up some ALPHA testing.

Iíd be interested in the alpha testing.
